Vincent Rivasseau

Vincent Rivasseau is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Vincent Rivasseau rather than just read about it. In short: Vincent Rivasseau (born 5 December 1955 in Talence) is a French mathematical physicist. Rivasseau studied from 1974 to 1978 at the École Normale Supérieure and then in 1978/79 at Princeton University with Arthur Wightman as advisor.

Key takeaways

Vincent Rivasseau belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Vincent Rivasseau to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Vincent Rivasseau from memory before moving on to harder problems.

Reference excerpt

Vincent Rivasseau (born 5 December 1955 in Talence) is a French mathematical physicist. Rivasseau studied from 1974 to 1978 at the École Normale Supérieure and then in 1978/79 at Princeton University with Arthur Wightman as advisor. In 1979 he got his PhD (Thèse de troisième cycle, Sommations et Estimations d'amplitudes de Feynman), at the Pierre and Marie Curie University, followed by the Thèse d'État (1982, Développements asymptotiques et méthodes graphiques en physique mathématique). From 1981 to 2001 he was a scientist of the CNRS at the Center for Theoretical Physics of École Polytechnique. Since 2001 he is professor of physics at the University of Paris-Sud in Orsay. Rivasseau's research deals with constructive quantum field theory and renormalization theory with applications to many-body theory, such as quantum interacting fermions in solid state physics. Since 2004 he has studied quantum field theories on noncommutative space-time, then group field theory. Since 2011 he develops the tensor track approach to quantum gravity based on random tensors (higher-dimensional generalizations of random matrices). From 2000 to 2012 he was editor in chief of Annales Henri Poincaré [1] and is currently co-editor in chief of Annales de l'Institut Henri Poincaré D [2]. He is committed to the development of science in Africa, being a co-founder of the AIMS-Sénégal Institute [3] (2011) and former president of the Association pour la Promotion Scientifique de l'Afrique [4], which he founded in 2009. He is also co-organizer of the Poincaré Seminars [5] at the Institut Henri Poincaré.

Worked examples

Example 1 — a first encounter with Vincent Rivasseau

Start with the simplest possible case. Write down what Vincent Rivasseau claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Vincent Rivasseau before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Vincent Rivasseau ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Vincent Rivasseau

In research: Vincent Rivasseau appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Vincent Rivasseau in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Vincent Rivasseau is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, French physicist stubs, French physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Vincent Rivasseau outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
